Another NotePad++ question

I bought the book " Head First HTML", and working on the lessons. I am using NotePad++ as my editor. I have entered this code as instructed:

<style type="text/css">
body {
background-color: #d2b48c;
margin-left: 20%;
margin-right: 20%;
border: 1px dotted gray;
padding: 10px 10px 10px 10px;
font-family: sans-serif;
}
</style>

In NotePad++, the word "type" is red in the editor, what dose this mean?
Also; when I load the page in FireFox, I see the boarder, but not in IE?

BTW - I really like the book so far.

Thanks
